The typical range for 2.4GHz WiFi is 150ft (46m) indoors, and 300ft (92m) outdoors. For 5GHz Wifi, it’s more like 50ft (15m) and 100ft (30m). The lower you set the power, the shorter the range – but the less you are blasted by the WiFi signal!

There’s no reason to leave the transmit power at maximum if you don’t need the range… As an added bonus, lower range means increased security since it’s less likely someone else will “see” your WiFi network.

Cell phones: they’re everywhere. From the “Battlephones” of the olden days, technology has progressed inexorably to today’s Smartphone. Crikey, some people even sleep with their cell phones!

Much has been written about the health effects of the gigahertz electromagnetic radiation that emanates from your trusty phone. Whether it’s brain cancer, or interfering with sleep, or mental fog, everyone has heard of some study or another that cell phones are dangerous.

Well, let’s get real: When you hold a microwave-frequency transmitter up against your head, what do you think is going to happen?! Of course, your average cell phone emits signals at power levels that are thousands of times weaker than a microwave oven – and at a different frequency. But still, cell phone emissions are nonetheless microwave radiation, and that can’t be good for you.

To make matters worse, your super-intelligent, handheld-computer “smart phone” just loves to gobble up the juice from its battery. But what if you could minimize your exposure to cell phone radiation and increase your battery life?

If you must use the darn things, you may as well do it correctly, yes?
